' Application filed July 20,

This invention relates to an improvement in burr extractors and cotton cleaners, and has for its objectto provide a machine of this character which first extracts the burrs and then cleans the Cotton, thereby reducing to a 1 minimum the motion'of cotton and enhancing the quality thereof and which also increases'the value of the cotton seed s nce the machine constituting the present invention and partly in longitudinal vertical-section will be hereinafter more fully describedand particularly pointed out in the appended claims, reference being had to the accompanying drawings forming a part ofthis specification, and in which:

Figure 1 isa view partly in side elevation showing a machine constructed in accordance with the present invention,

Figure 2, 's a view in transverse vertical section of themachine shown in Fig. 1, and s Figure 3 is a view in end elevation. s

Referring to the drawings the numeral 1 designates a suitable casing or housing mounted on a suitable-frame 2. [The cotton is fed into a breaker, designated generally at 3 having an opening 3' and having a toothed breaker element 4 rotatedin the breaker casing by means of a shaft 5 and cooper-able with a toothed breakerplate 6 adjustable towardand away from the drum 4 by virtue of its mounting on bolts 7 fixed to the breaker housing and extending through openings in o the plate 6 and by virtue of the provision of nuts 8 on the bolts 7, the nuts 8 serving to tension the coil 'springs9 which press the plate 6 towardthe breaker element 4; 1

' After passing through the breaker the cotf ton drops-onto a spiral conveyor-1O extending longitudinally througnthe housing 1. The

' breaker 3 is located at one end of the machine and the cotton which drops there-from onto the conveyor 10 iscarried theentire lengthof the machine and then dropped Onto the 1925. Serial 110.44,,833,

and 12 are of identical construction andeach includes an axial shaft 13 and radial teeth 1 1 extending spirally around the shaft 13. The conveyor 10 operates in conjunction with a trough or arcuate Way15'and the combined pickers and conveyors 11 and 12 operate in conjunction with similar though perforated Ways and troughs, designated at 16 and 17.

Rota'ry'saw assemblies 20 and 21 are cooperatively mounted with respect to the conveyors 10, 11' and 12. Strippers 22 and 23 are co-operatively"disposed with respectjto the sawassemblies 20 and 21; Brushes 24 the saw assemblies.

and 25 extendlongitudinally: of the casing and are carriedby shafts 26, 27, 28, 29, I and 31, respectively; The trough 15is im -f perforate from the end at which it receives the cotton from the breaker to its Opposite endand where 1t'1s provided w th an open- A to permit the cotton to'd'rop onto the combination pickers and conveyors 11 and 12.

The troughs 16 and 17 are perforate or of, screen from the end at'which they receive the cotton from theconveyor lO to their 01- posite end which underlies the breaker and they are provided with openings B to permit the burrs to drop into a discharge trough and 25 are'also cooperatively associated with g The saw assemblies 20 and 21, strippers 22 and 23 and brushes 24;

in. which a spiral discharge conveyor 36.0p-

crates. The cotton. whichis delivered from the breaker 3 to the conveyor 101s carried by the saw assemblies. The saws of the saw assembl es pick up thevcotton andany-burrs .90 p I the conveyor 10 along the" machinebetween 1 that are takenv up are thrown froni'the saw assemblies back'to'the conveyor 10' by the strippers 22 and 23. The cotton after havingpassed through the conveyor 1O is delivered' to the combination pickers andconvej ors 11 and 12 and the burrs remaining with the cotton are also delivered to the combination pickers and-conveyors. 11 and 12; The

saws ofthe saw assemblies also pick up the cotton remaining on j the combinationfconveyo'rs and pickers 11'and12 and any burrs that'are'picked upoare knocked off of the saw assemblies bythe strippers. The tendency of the burrs, trashand foreign matter when delivered to the combination'conveyors and ton which is picked up by the saw assemblies is removed from the saw assemblies by the brushes 2% and and slides down chutes and 11 onto transversely extending spiked cylinders 42 mounted on shafts 13 extending across the casing and operating over a screen 44, whereby the cotton is further cleaned and V dirt, shale, trash or other foreign'matter remaining with the cotton passes througl'i the screen 44 into a hopper' lh from which it is discharged by a spiral conveyor-46.

Referring to Figure 1, one of the shafts 43 of the spiked cylinders is directly driven and the remainingcylinders are driven from said first mentioned cylinder by means of overlapping bolts 17 engaging pulleys mounted upon the shafts of the respective cylinders. A sprocket chain engages sprockets mounted upon the shaft of the conveyor 10, the saw shafts 26 and 27, the strippershaft 28, the shafts 13 of the combined pickers and conveyors and the shaft 31 of one of the 1 brushes and over a tensioning sprocketwheel 52, and serves to drive these parts. A pulley wheel 53 mounted upon the shaft 29 of one of the strippers and a pulley Wheel 55.

mounted upon the shaft 28, of the other stripper are engaged by a twisted belt 56' whereby the stripper 23 is actuated. The shaft 30 of one of the brushes carries a pulley 57 andthe shaft 31 of theother brush carries .a similar pulley, which pulleys are. engaged by a twisted belt58 so that the. brush 2% is operated from the shaft 31. The shaft 5 of the breaker is driven from the shaft 29 by meansof sprockets 59 and 60 mounted on said shafts and a sprocket chain 61 engaging over said sprockets. The shaft 30 of the brush 2 1- carries a second pulley wheel 62 and the shaft of the conveyor 36 carries a pulley wheel 63. Over the pulley wheels 62 and 63 travelsa belt 6% for operating the conveyor shaft. The shaft of the conveyor 36 is provided with a second pulley wheel (35 and the shaft of theconveyor 4:6 is provided witha pulley wheel 66. a A belt 67 engages the pulley wheels 65 and66 to operate the conveyor 46.

In this manner all of the parts may be drivenfrom a single directly driven shaft as found most convenient.
